Abstract
A pump delivery system including a pump mechanism for delivering liquids under pressure while also producing a pulsating output during operation, and a pump pulsation dampening attachment for dampening the pulsating output of the pump mechanism. The pump pulsation dampening assembly includes a pressurized vessel having an interior surface defining a chamber for receiving the liquid from the pump mechanism, the chamber also containing a pocket of pressurized air therein for absorbing the pulsating output generated by the pump mechanism.
